Definitions

  • the invention relates to an intra-ocular implantable device and to a method of surgically implanting such device in the posterior chamber of a human eye.
  • Surgical removal of opaque lenses from the eyes of cataract patients is one of the most common surgical procedures. After such surgery, contact lenses or spectacles are usually prescribed to provide at least limited vision for the patient. While spectacle lenses and contact lenses have a number of optical drawbacks, the ready ability to remove or replace them if defective makes them safe and attractive . appliances.
  • lens For some patients, however, spectacles and contact lenses are not workable. Many older patients are unable to insert and remove the • contact lenses or even handle the thick spectacles. The same is true with very young patients. Fortunately for such patients a surgical alternative is available — implantation of a prosthetic or artificial lens into the interior of the eye to replace the opaque natural lens which has been surgically removed. While this type of surgery for all cataract patients may not be appropriate now, improvements in lenses and techniques, such as the present invention, may make such surgery universal for cataract patients in the future. This operation is called lens
  • the Shearing intra-ocular lens which is described in U.S. Patent 4,159,546, uses a pair of spring-like loops on either side of the lens (optic) which are positioned in the area between the iris and the ciliary body known as the ciliary sulcus.
  • the Shearing lens is plano-convex with the plane surface designed to contact the posterior capsule or surface of the natural lens, which " membrane is normally left intact but often perforated (discissed) , during extracapsular cataract extraction (ECCE) .
  • the optic portion of the Shearing lens is circular.
  • the Shearing lens is similar in construction to an earlier device of Barraquer, but which was designed for placement in the anterior chamber.
  • the U.S. patents to Poler 4,073,014 and 4,080,709 are other examples of posterior chamber devices..
  • the present invention relates to a unique implantable intra-ocular device having a number of substantial advantages over prior art devices, including the device of Shearing.
  • two haptic loops are attached to a lens, opposite each other.
  • at least one of the haptic loops is compressable, and preferably both can be compressed.
  • the lens is designed for fixation in the ciliary sulcus, the unique compressability of the haptic loops achieved by using dissimilar thicknesses . ..in the upper and lower loops make the present invention also suitable for insertion in the capsular "bag", (this is the remmant of the capsule of the natural lens, after extracapsular cataract extraction).
  • the lower loop has a stiffness greater than that of the upper loop.
  • the experience has been that when an implantable device displaces from its desired position, it tends to move downward, or if the pupil is assymetric the latter tends to peak upwards.
  • Providing the lower haptic loop with a. greater stiffness ensures that the device will remain in a proper position, and the optic will occupy all or most of the pupillary aperture.
  • the lens of the present invention has a vertical dimension greater than its horizontal dimension. Since decentering as noted above tends to be movement in the vertical direction, making
  • O PI that dimension greater also helps ensure that the lens will be maintained in a position to satisfactorily carry out its function.
  • Implantation can either take place at the time the cataract is removed, i.e., primary implantation, or during a second operation subsequent thereto, i.e., secondary implantation.
  • the posterior capsule or surface of the natural lens is usually left intact, but is often perforated to guard agains the possibility that it will later become opaque. If that occurs the perforation will allow a distinct image to impinge on the retina to provide satisfactory, vision. This step of perforation is called dis ⁇ ission.
  • dis ⁇ ission This step of perforation.
  • the normal procedure is to carry out discission after the implanted lens has been put in place. After the nucleus and cortex of the natural lens has been removed, the pressure of the vitreous fluid behind the natural lens capsule often pushes that posterior surface forward.
  • the membrane presses directly against the plane rear surface of the lens, which can make discission a difficult operation without decentering the lens and/or getting vitreous fluid into the anterior chamber.
  • This problem is much reduced by the present invention in which the rear surface of the lens is convex, providing sufficient room to carry out discission without difficulty.
  • the optical characteristics of the lens of the present invention are believed to be improved by making the rear surface convex and the front surface piano.
  • the front surface of the lens is provided with at least one, and preferably upper and lower, angulated bores which extend into the lens at an angle to the vertical of, for example, 15 Q to 20°. In the past it has been conventional to insert the device into the eye using forceps.
  • the implant can be fixated at either the upper or lower angulated bore with either a fine spatula or forceps and maneuvered interiorly into position.
  • the lens is provided with straight line portions in the lateral edges of the optic. These straight edges not only minimize the incision required to insert the implant but also guide the lens into position as it is inserted. Lenses having a circular shape, such as the Shearing lense, may have some tendency to go off center during insertion, as their maximum diameter clears the incision internally. To implant the device of the.
  • an air bubble (or other substance to form the anterior chamber) is usually placed in the anterior chamber and the device slid into the chamber behind the bubble through a corneal- scleral incision.
  • the device is then moved inferiorly so that the lower loop compresses in the inferior ' (lower) ciliary sulcus. Inferior movement can then be continued with the lower loop compressed until the upper loop clears the pupillary margin. If necessary to clear the
  • the upper loop can also be compressed using a second instrument, or the upper iris can be retracted.
  • the device springs into place and will be held without suturing, (though a suture can be used through the upper loop) .
  • An angulated bore is preferably provided in the lens for permitting ready manipulation of the lens within the eye with a fine spatula or other instrument.
  • the device of the present invention can be implanted with relative ease- by either a right or a left-handed surgeon.
  • Figure 1 shows a front view of the device of the present invention.

  • Figure 4 shows a further schematic view of the present invention with the lower haptic loop being compressed in the inferior ciliary sulcus by a spatula or similar instrument engaging the upper angulated bore.
  • Figure 5 shows a schematic view of the present invention with the implant moved inferiorly behind the pupillary margin.
  • Figure 6 shows a schematic view of the present invention with the implant sprung into the desired position behind the iris with the loops in the ciliary sulcus and the discission being carried out behind the lens.
  • the device of the present invention is comprised of an ovoid shaped lens 20 of suitable material, upper haptic loop 22 attached to lens 20 and lower haptic loop 24 also attached to lens 20.
  • the two haptic loops may be inserted into drill holes or molded with the optic and are fixed in place at the periphery of lens 20 opposite each other.
  • the edge of the lens between the two loops includes straight lines portions 26 and 28 which, as noted above, aid in guiding the lens into position through a small incision.
  • the lower haptic loop 24 acts like a spring during insertion of the device as explained in detail below.
  • Angulated bores 30 and 32 are provided in *• the front surface of lens 20 for fixating the device to a fine spatula or other similar instrument to properly insert and position the lens, avoiding trauma to the corneal endotheliura. An angle of 15° to 20° to the vertical is believed satisfactory.
  • the lower loop 24 has a greater stiffness than upper loop 22 to ensure the lens centers after insertion.
  • This differential stiffness can, for example, be provided by making the upper loop of 5-0 polypropylene or nylon and the lower loop of 4-0 polypropylene or nylon or other bio-acceptable material. Since displacement after implantation when it occurs is usually vertical, acceptable optical function is also enhanced by making the 5 lense ovoid with a vertical dimension greater than its horizontal dimension, thus occupying the pupillary aperture with the lens optic.
  • Upper loop 22 is preferably closed by being fixed at-both ends, unlike the Shearing

Abstract

Dispositif implantable intra-oculaire et procédé d'implantation chirurgicale d'un tel dispositif consistant à attacher sur les faces opposées d'une lentille (20) des anses haptiques supérieure et inférieure (22, 24) en contact avec le sillon ciliaire (ou sac capsulaire) pour positionner la lentille ou cristallin dans la chambre postérieure. La lentille (20) possède une dimension dans une direction transversale supérieure à sa dimension dans une direction perpendiculaire. L'anse inférieure (24) possède une rigidité plus grande que l'anse supérieure (22) et la lentille (20) possède une dimension verticale supérieure à sa dimension horizontale pour assurer un bon positionnement de la lentille. La lentille (20) possède une surface convexe arrière facilitant la discission après implantation et procurant des avantages optiques. Des alésages supérieur et inférieur (30, 32) aménagés dans la surface antérieure de la lentille s'étendent en faisant un angle par rapport à la verticale de 15o à 20o par exemple pour permettre la manipulation à l'aide d'une fine spatule du dispositif ainsi que la fixation de ce dernier pendant l'implantation. Les bords de la lentille entre les anses comprennent des parties linéaires droites (26, 28) permettant de guider le dispositif pendant son insertion et nécessitant une incision minimum.
